It is invalid, but not for the reason you state.
The problem is that `int_fast32_t` is supposed to be '''signed''', while
`unsigned long` is '''unsigned'''. As for size, the type `int_fast32_t`
is required to be ''at least'' 32 bits, not ''exactly'' 32 bits, so the
following would be correct, both on 32-bit and 64-bit machines:
{{{
typedef long int_fast32_t;
}}}
In fact, on my 64-bit Linux laptop, the types `int_fast16_t` and
`int_fast32_t` are `typedef`ed to be 64-bit `long`s.
